HP 35s Scientific manual Parts of Numbers, Integer part, Fractional part, Absolute value

Parts of Numbers

These functions are primarily used in programming.

Integer part

￿To remove the fractional part of x and replace it with zeros, press  (). (For example, the integer part of 14.2300 is 14.0000.)

Fractional part

￿To remove the integer part of x and replace it with zeros, press  (). (For example, the fractional part of 14.2300 is 0.2300)

Absolute value

To replace a number in the x-register with its absolute value, press . For complex numbers and vectors, the absolute value of:

1.a complex number in rθa format is r

2. a complex number in xiy format is x 2 + y 2

3.a vector [A1,A2,A3, …An] is

Argument value

A

= A 2	+ A	2 + ⋅ ⋅ ⋅ + A 2
1	2	n

To extract the argument of a complex number, use =. The argument of a complex number:

1.in rθa format is a

2.in xiy format is Atan(y/x)

Sign value

￿To indicate the sign of x, press (). If the x value is negative, – 1.0000 is displayed; if zero, 0.0000 is displayed; if positive, 1.0000 is displayed.
